Application filed July 2, 1913. Serial No. 776,988.

To all whom it may concern:

Be it known that I, IsAAc'BER'rIN, a subject of the Czar of Russia, and residing at New York, in the county of New.York and 5 State of New York, have invented certain new and useful Improvements in Scrap Removing or Discharging Mechanisms for Paper-Dish-Making Machines, of whichthe following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making paper dishes and is an improvement on the machinescovered by U. S. Let- 15 ters Patent No. 939,888, granted tome Nov. 9, 1909; and U. S. Letters Patent No.

970,168, granted to me September 13, 1910.

The machines of the class referred to, or covered by the Letters Patent specified are used in making paper dishes from longstrips of paper which are fed into the machines and from which blanks for dishes are cut, scored and slitted, after which'saidblanks' are fed into a shaping and forming mechanism by which they are folded into. dish form and the se arate parts thereofinterlocked or secu'r together. In this 0 eration scrap material is detached from t e paper strip and this material, ifnot removed or discharged, enters into themachine and clogs or interferes with the operation thereof, and the object of this invention is to provide sim 1e and efiective means for removing or disc arging the said scrap material from the operating table of the machine sons to avoid the above objectional results.

The invention is fully disclosed in the following specification of which the accom-' panying drawings form apart, in which the separate parts of my improvement are designated by suitablereference characters in each of the views, and in which Figure 1 is a plan viewof that art of a machine of the class specified w ich is provided with my improvementy-Fig. 2 a partial transverse vertical section on the line 22 of Fig. 1; Fig. 3 a partial'section on the line 3-3 of Fig. 2; Fig. 4 a view similar to Fig. 2 but showing only a portion thereof and showing the part therein in a- 5 a view similar different position, and; Fig.

to Fig. 4 but showing the parts'ina still different position.

Machines of the class specified involve a strong. substantial frame comprising, in

part, parallel side members a, and a table b mounted preferably in section, but the frame and table, are similar to those shown and described in the patents hereinbefore referred to and form tion. The said machines also'involve two roller dies 0 mounted transversely of the machine and above and below the table 6 and one of which is shown in full lines in Fig. 1, and both of which are-indicated in dotted lines in Fig. 2, and rearwardly of the roller dies'c are two main feed rollers at only one of which is shown, and rearwardly of the main feed rollers d are two supplemental feed rollers e only one of which is shown. 'The feed rollers d and e are also mounted above and below the table I), and

no part of this invenin practice a strip f of paper is fed into the machine between the rollers c, and d'and e, the rollers 0 0 rating as roller dies, and the rollers d an e operating only as feed rollers.

The topmain feed roller (1 iscarried by links 03* mounted on'the trunnions of the top roller die 0 and the top feed roller e is mounted in links (2 which are mounted on feed roller d, andthe trunnions of the top by means of this construction the top feed roller 6 and the top feed roller d may be turned upwardly and backwardly whenever desired for the purpose of cleaning the ma-' chine, or for any other purpose, and in this operation the bottom rollers 03 and 6 remain stationary.

As in Patent No. 939,888, the machine is driven ;by a main drive shaft 9 mounted below the roller dies 0 and provided at one end with' a. drive wheel 9 and the shaft 9 is also provided with alarge mutilated gear g which meshes with a mutilated gear 9 on the corresponding trunnion of the bottom roller die 0, this construction being similar in all respects to the driving mechanism shown and described in said patent. In

this case, the end trunnions of the rollerdies 0 opposite the gear 9'' and g are provided with elongated gears g and the-feed rollers d and e are drlven by positive gearing, parts of-which are shown at g", this gearing bein the same as in another appli cation filed y'me of equal date herewith Serial- No. 776,936 and covering a feed mechanism for paper dish making machines, but it will beunderstood, however, that the feed rollers 12 and 0 may be driven in any angular recesses f between the separate desired manner, or by a construction similar l this invention and is therefore not shown to that in the patents hereinbefore referred to.

In the operation of a machine of this class, the strip 1 is fed into the machine, as in the patents hereinbefore referred to, and the dish forming blanks f and f are cut therefrom, said dish forming blanks being provided with score and foldinglines f and with slits f and in forming these blanks triangular scraps f are cut from the strip f and when removed they form triblanks, and the object of the inventionor' improvement which forms the basis of this application is to remove said scraps f and discharge the same below the table of the machine, or below the main operative mechanism thereof.

The main shaft 9 is provided centrally thereof and centrally of the bottom por- ,tion of the machine with a beveled gear h which meshes with a corresponding beveled gear k on a cam shaft 71/8 mounted longitudinally of theframe of the machine, and supported in any suitable manner by supports, one of which is shown at h inFig. 3. The shaft 11. is provided with a cam h provided in one face with cam grooves h and k? the forms of which are clearly shown in 7 Fig.9.

Mounted at the opposite sides ofthe frame and forwardly of the main feed rollers d and supported in any desired manner are vertically movable sleeves i the lowen ends of which are connected by a cross bare A provided with a pin 71 movable in the groove h of the cam h, and movable vertically in the'sleeves i are rods j the lower ends of which are connected by a cross bar j provided with a central standard i having a pin 9" movable ina roove k of the cam h.

The upper ends 0 the sleeves i are provided with heads kthrough which the rods j are vertically movable and the heads is of the sleeves i are provided with inwardly set jaws; I0 and secured to thetops of the rods j are cross heads m'having downwardly directed' fingers m which operate in connection with the jaws k to grasp and hold the scraps j which are cut from the 'sheet of material f. The heads k of the sleeves i are also provided with chutes n which are secured thereto and which extend downwardly and forwardly, and the table 12 is cut out over the tops of the chutes n to form recesses m downwardly through which the scraps f are moved or carried by the parts k and m and dropped into the chutes n.

It will be understood that the means for shaping and forming the blanksf and f into dishes is located rearwardly of the feed rollers e, as in Patent No. 939,888, herein;- before referred to, and said dish forming and shaping mechanism forms no part of and described.

The operation of the roller dies 0 and feed rollers d and e is intermittent, and the operation of the scrap detaching and removing devices is also intermittent as will be readily understood from the foregoing description, when taken in connection with the accompanyin drawings and the following statement t ereof. At each intermittent movement of the feed mechanism, above described, the strip f is fed into the machine a distance approximately equal to the width of one of the dish blanks and f, and corresponding scraps at the opposite sides of the strip f are drawn into position overlying the recesses n and in which position they may be operated upon by the jaws k and fingers m which are held normally in the position shown in Fig. 5. At the end of each intermittent movement of the feed rollers and roller dies, the cam operated mechanism consisting of the sleeves i and the cross bar i and the rods 9' and the cross bar 7' are moved, one up and the other down, to the position shown im Fig. 2, so that the jaws k and fingers m will grip the scraps f. The continual movement of the cam mechanism moves the sleeves i and the rods j downwardly into the position shown in Fig. 4, carrying the scraps f downwardly through thetable b, as shown in said figure, after which the continual movement of the cam mechanism moves the sleeves i and rods 1' in opposite directions, or returns them to their normal position, which operation releases the scraps f and allows them to drop into the chutes n.

The front edge of the table I) is indicated at b in 'Fig. 1, and forwardly of the roller dies 0, suitable guide plates 0 are provided to support and guide the strip f into the roller dies, but these guide plates also form no part of this invention.

My invention is not limited to the connection of the chutes n with the vertically movable sleeves 2', nor to other exact details of the construction herein shown and described, and various changes therein and modifica- -tions thereof may be made, within the scope vided with a horizontal table having recesses at its opposite sides, vertically movable members mounted at the opposite sides" of the machine and provided at their upper ends withjaws, other vertically movable members mounted at the opposite sides of the machine and provided with fingers adapted to operate m connection with said jaws to grasp and hold scraps cut from the strip of paper passed over said table, and chutes into which said scraps are discharged by said vertically movable members.

2. A machine of the class described provided with a horizontal table in the opposite side portions of which are recesses below which are-scrap discharge chutes, vertically movable sleeves mounted at the opposite sides of said table and provided at their upper ends with jaws, rods vertically movable through said sleeves and provided at their upper ends with fingers which operate in connection with said jaws to detach scrap pieces cut from said strip and discharge the same into said chutes.

3. In a machine of the class described, a horizontaltable provided with recesses in its opposite side edges, means for feeding a strip of paper over said table, devices a mounted above and below said table for grasping and holding scraps cut from. said strip of paper as it passes over said recesses,

and chutes into which said scraps of paper are discharged by said devices.

4. In a machine of the class described, a horizontal table provided with recesses in its opposite side edges, means for feeding a strip of paper oversaid table, devices mounted above and below said table for grasping and holding scraps cut from said strip of paper as it passes over said recesses, and chutes into which said scraps of paper are discharged by said devices, one of said devices. being stationary and the other vertically movable.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing witnesses this 28thday of June 1913.
